9/10. On a school test that wouldn't be a bad grade, but on the Internet that one wrong answer could have compromised my identity.
But just remember. Unless you got a 10/10
when you knew one of the options was a scam, everyone really needs to be more careful online. And saying that "I usually browse safer in the real world" is like saying that "I usually don't speed" when you just got pulled over by the cops. You were caught with your pants down, and making excuses on it doesn't solve anything. All it takes is for everyone to let their guard down for one second to compromise everything.
(Yes, I did get the PayPal email wrong myself, but (pardon this sounding hypocritical to my previous statement) I never use PayPal, and I couldn't check the URL of the link to the login page as the example was just a screenshot. One quick glance to the status bar revealing a website other than https://www.paypal.com/... would have been an instant red flag to me.)
I got the Nigerian 419 and SSL questions right. I know you can spoof SSL certificates if you really want to, and I saw this good video from ABC News about the Nigerian 419 scams last year:

I also know anything in life that promises a small investment for a large return is either a fake pyramid scheme, or a Nigerian 419 scam. Think about them with common sense; if you have $10 million USD in some 'locked' bank account that could be had for only a few thousand dollars, why wouldn't you just go to a bank and take out a loan for that amount yourself? If there really was $10 million, why would you let some random Joe Schmoe get the money when you'd be able to payback the loan without problems? Duh...
Just use common sense, sound judgment, and always check those links!
